问题描述

这里的代码我能够正确读取消息，只要收件箱中存在短信xxxxxxxxxxx，但是当xxxxxxxxxx没有短信时，应用程序崩溃如何检查收件箱中是否存在xxxxxxxxxx的短信

here is the code i am able to read the message correctly whenever a sms against xxxxxxxxxxx is present in inbox but when there is no sms for xxxxxxxxxx the app crashes how do i check if sms for xxxxxxxxxx exists in inbox

StringBuilder smsBuilder = new StringBuilder();
        final String SMS_URI_INBOX = "content://sms/inbox";
        final String SMS_URI_ALL = "content://sms/";
        try {
            Uri uri = Uri.parse(SMS_URI_INBOX);
            String[] projection = new String[] { "_id", "address", "person", "body", "date", "type" };
            Cursor cur = getContentResolver().query(uri, projection, "address='xxxxxxxxxx'", null, "date desc");
            if (cur.moveToFirst()) {

                int index_Address = cur.getColumnIndex("address");
                int index_Person = cur.getColumnIndex("person");
                int index_Body = cur.getColumnIndex("body");
                int index_Date = cur.getColumnIndex("date");
                int index_Type = cur.getColumnIndex("type");
                do {
                    String strAddress = cur.getString(index_Address);
                    int intPerson = cur.getInt(index_Person);
                    String strbody = cur.getString(index_Body);
                    long longDate = cur.getLong(index_Date);
                    int int_Type = cur.getInt(index_Type);

                    strMessage=strbody;

                    smsBuilder.append("[ ");
                    smsBuilder.append(strAddress + ", ");
                    smsBuilder.append(intPerson + ", ");
                    smsBuilder.append(strbody + ", ");
                    smsBuilder.append(longDate + ", ");
                    smsBuilder.append(int_Type);
                    smsBuilder.append(" ]\n\n");
                } while (cur.moveToNext());

                if (!cur.isClosed()) {
                    cur.close();
                    cur = null;
                }
            } else {
                smsBuilder.append("no result!");
            } // end if
        }catch (SQLiteException ex) {
        //Log.d("SQLiteException",
        ex.getMessage();
    }

推荐答案

检查此解决方案。所有你需要的编辑它以检查来自该特定号码的消息是否存在。我的意思是检查光标c 是否存在。

Check this solution. All you need to edit it to check messages from that particular number exists or not. I mean check whether Cursor c exist or not.

Cursor c = cr.query(myMessage, new String[] { "_id", "address", "date",
                "body", "read" }, "address = '+9180009'", null, null);

阅读收件箱信息一个特定的数字 [ ^ ]
